Abstract
A new asterosaponin, named helianthoside (1), has been isolated from t he butanolic extract of the starfish Heliaster helianthus and its stru cture established on the basis of extensive spectroscopic experiments and chemical correlations. Helianthoside is the first asterosaponin wi th a C3'-sulphated xylopyranose. The absolute stereochemistry at C24 w as determined by the Trost-Mosher method.
